Although the then-Selangor MACC deputy director Hishamuddin Hashim had disclaimed active involvement in the graft busting operation which led to the death of Teoh Beng Hock, the royal commission of inquiry (RCI), however, found that he had played an instrumental role in the tragedy.

According to the report, contrary to his testimony, Hishamuddin was found to have been in full control and actively involved in the entire operation from the very start.

The commission discovered that during the period of the operation, the officers involved would keep him updated twice in a day when he would give them specific directions.
